STEP
1 Maximum current measured as a multiple of the rated current of the protection.
The value of the register is updated, if one of the following conditions are fulfilled.
1) The measured current value exceeds the value already in the register.
2) The I > stage or the I
0
moment of operation is recorded in the register.
2 Number of starts of the low-set current stage I
3 Number of starts of the high-set current stage I
4 Duration of the latest start situation of stage I
time t>. A new start resets the counter which then starts counting from zero. When
the concerned stage has tripped, the counter reading is 100.
5 Duration of the latest start situation of stage I
time t>>. A new start resets the counter which then starts counting from zero. When
the concerned stage has tripped, the counter reading is 100.
0 Display of blocking signals and other external control signals. The rightmost digit
indicates the state of the blocking inputs of the module. The following states may
be indicated:
0 = no blockings
1 = tripping of the low-set stage I
2 = tripping of the high-set stage I
3 = tripping of both protection stages blocked
The mid digit is permanently zero. The leftmost digit indicates the state of the
remote reset input, if the protection relay is provided with one. The following states
may be indicated:
0 = remote reset control input not energized
1 = remote reset control input energized
From this register it is possible to move on to the Trip test mode, where the start
and operate signals of the module can de activated by force one by one. For further
details, see manual "General characteristics of C type relay modules".
A Address code of the protection relay module, required by the serial communi-
cation system. Register A has three subregisters with the following contents:
1) Selection of data transfer rate for the serial communication. Selectable values
300, 1200, 2400, 4800 or 9600 Bd. Default value 9600 Bd.
2) Communication interruption counter. If the relay module is connected to a
communication system, which is in operation, the value of the communication
interruption counter is 0 (zero). If the communication system is disturbed, the
numbers 0...255 are scrolling in the communication interruption counter.
3) Password required for remote setting of relay module parameters.
When the display is dark, the beginning of the
display menu can be reached by pushing the
STEP push-button once.
The registers 1...5 are reset by pressing the push-
buttons STEP and RESET simultaneously or
via the SPA bus using the V102 command. The
registers are also reset if the auxiliary power
digits the value of the register.
